Patent EP-0113692-A3 (EP)
IPC: B29C45/14
Filed: 1984-01-04
Abstract: A molding apparatus (10) has first and second opposed 
mold surfaces (22, 26) with the first mold surface (22) having 
a feed runner network (24). A mold structure (30) is 
supported by the second mold surface (26) and is spaced 
from the first mold surface (22). The mold structure (30) is 
adapted to hold a lead frame strip (38) and objects (39) held 
thereby in a plurality of openings (36). A gate plate (44) fits 
between the first mold surface (22) and the mold structure 
(30). The gate plate (44) has a plurality of gates or apertures 
(50) from a first (46) to a second (48) outfacing surface 
portion (46, 48) thereof. Set feed runners (71) can be 
removed from the molding apparatus (10) by motivating the 
gate plate (44) laterally across the mold structure (30). The 
runners are generally removed from the gate plate (44) by 
bending the gate plate (44) over a cylindrical surface (61) of 
small enough radius so that the set runners (71) cannot 
follow and are forced to separate gradually from the gate 
plate (44), eventually becoming completely free and falling 
away from the molding apparatus (10). The apparatus (10) is 
particularly adapted for automation and allows more mold­
ing cycles per unit time and wastes less encapsulating 
material than does prior apparatus. A molding method 
utilizing the gate plate (44) is likewise set forth.
Patent EP-0149290-A3 (EP)
IPC: E21B21/10
Filed: 1984-01-13
Abstract: In an intermittently rotating down-hole drilling tool a 
closed valve (17) is operatively moved downwards by 
pressurised drilling mud pumped down the drill string (11), 
the valve when it attains its lower position being opened and 
being returned under the influence of a spring (40) or other 
upward urging means acting on the valve to its upper 
position at which the valve is closed, thereby completing the 
cycle of operations. The valve is continuously coupled to a 
torque member (71) such that the downward movement of 
the valve causes the torque member to turn in one direction, 
and the upward movement of the valve causes the torque 
member to turn in the opposite direction. A drill bit (103) 
mounted on the lower end of a rotor (75) is connected, by 
means of a one-way clutch (76), to the torque member so 
that during the downward movement of the valve the rotor 
and drill bit are rotatably driven by the torque member but 
are stationary during the upward movement of the valve, the 
drill bit thus being operatively intermittently rotated. During 
the upward movement of the valve the pressurised drilling 
mud flows through the open valve and issues from the drill 
bit as high pressure and volume flushing jets while the drill 
bit is stationary, thereby providing a more effective cleaning 
of cuttings and chips from the bottom of the bore hole being 
formed by the drill bit. Aligned annular grooves (87, 88) are 
provided in the rotor and in the housing in which the rotor is 
mounted, ball bearings (89) being partially disposed in each 
of these grooves, thereby to provide an axial thrust bearing 
(86) capable of transmitting high axial thrust from the 
housing to the rotor and hence to the drill bit. Lipped pockets 
(90) are also provided in the rotor in communication with the 
grooves therein, with the ball bearings being disposed within 
these pockets during assembly and disassembly of the rotor 
and housing.

IPC: G06F3/033
Filed: 1985-03-14
Abstract: A method and device for instituting mode changes (78) 
or precise relative cursor (13) positioning is taught. Briefly 
stated, an operator who is interfacing with a CRT (10) or 
display area (12) which has a touch input device (51) on it, 
such as a switch matrix or infrared light beam matrix, may 
institute a number of changes simply by inserting two or 
more noncontiguous styli (18,18), such as two fingers, into 
the touch input area. This would, therefore, change the mode 
of information which is presented by the display to the op­
erator (16) or the information presented to a computer or 
interface via the display area by the operator. In the preferred 
embodiment, the insertion of two noncontiguous fingers 
would allow the cursor (13) to be moved in a speed and 
direction which is directly related to the speed and direction 
of a finger with the result that the cursor need not be disposed 
directly under the finger which might otherwise block an 
operator's view and thereby allow more precise positioning 
of the cursor.

Title: An internal combustion engine having low octane number requirements
IPC: F02F3/14
Filed: 1986-11-04
Abstract: The invention relates to a spark-ignition internal combustion engine having a combustion chamber which, at least in part, presents surface areas (10) which have been treated to reduce the octane number requirement of the engine. 
<??>The surface area to be treated may, for example, be either blasted or etched to produce surface depressions, and is then flame sprayed with copper particles to form heat-reflective surfaces. At least this latter method results in solely low-temperature heating of the walls of the combustion chamber, which can be advantageous in the case of diesel engines, but not in the case of Otto-cycle engines. 
<??>The improvement in such engines afforded by the invention is that the surface areas (10) are instead provided with at least one layer (12) which presents to the combustion chamber (1) a defining surface (9) which exhibits an extremely low reflectivity to electromagnetic waves in the wavelength range of about 0.2-7.0 microns, and which also results in diffuse reflection of non-absorbed incident waves (14).

Title: Method and apparatus for molding articles
IPC: B29C45/66
Filed: 1987-05-02
Abstract: Method and apparatus for injection compression molding of thermoplastic parts. A preferred apparatus (100) includes a platen assembly 106, a toggle clamp assembly 102, a screw injection assembly 101, a hydraulic system suitable for providing power to the toggle clamp assembly 102 and the screw injection assembly 101, and a control system 88 for operatively controlling the various hydraulic devices associated with the molding apparatus. The platen assembly 106 provides for a plurality of variable-volume mold cavities 7. In one embodiment, enlarged mold cavities 7 receive plasticized resin from the screw injection assembly 101, and compression of the injected resin is provided by the toggle clamp assembly 102. In another embodiment, the platen assembly 106 includes a floating die assembly wherein pressure created by injected resin causes die inserts 5 and support pillars 15 to slide relative to a molding plate 74. Compression in this embodiment is also preferably provided by the main toggle clamp assembly 102. Preferably, the toggle clamp assembly 102 provides multiple-stage compression of the resin to first redistribute the resin and vent the cavities and, second, compress the resin to compensate for cooling-induced shrinkage thereof. In the multiple cavity embodiment, because all cavities 7 are equally compressed simultaneously, control of the molding process and balancing of the mold are readily accomplished. The method and apparatus are particularly well suited for molding optical lenses and disks. Printed circuit substrates can also be molded thereby.
